VTI is conducting full-scale load tests and accelerated testing of roads.
With our Heavy Vehicle Simulator (HVS) machine, we can simulate real loads from heavy vehicles, and thereby study how various types of road structures manage under heavy traffic.Our high-capacity equipment makes it possible, in many cases, to simulate a year of heavy traffic in less than a week. Wheel load can vary from 3 to 11 tons (30–110 kN), corresponding to 6 to 22 tons axle load. We can also vary tire pressure, speed, load direction, lateral position, and temperature according to existing need.The HVS machine is mobile, which means that it can be used both at special testing facilities and on existing roads. For short distances it can move on its own; for longer distances it can be towed.We offer:
* The road bed is scored with sensors for such things as pressure, linear strain, and deformation. The responses from these sensors are registered during systematic variation of the test parameters. This provides a large amount of measured values that can be used in evaluating various road structures, as well as for development and validation of theoretical models.

Achieving the national and international environmental objectives for maritime airborne emissions requires a combination of new and more powerful policy instruments. The policies already in place are not enough. This is one of the conclusions of a research...
Large, electrified aircraft is far off in the future. On the other hand, there may be potential for a new market with smaller regional flights. These are the conclusions of a literature survey made by researchers at VTI.
The need for standardisation is increasing as electric road systems are reaching higher levels of maturity. A large part of the standards for intelligent transport systems (ITS) assessed in a new VTI and SIS study was considered potentially useful for...
Although we know that tyre and road surface wear generates significant emissions of microplastic particles, knowledge about them is very limited. This is the conclusion of a report issued by the Swedish National Road and Transport Research Institute (VTI).
The effect of climate change will result in more extreme weather events causing for example increased risk of floods, and landslides, which will result in great costs to society. Therefore, society needs to prepare for the consequences brought on by climate...
VTI has developed a train simulator that has become a valued tool in train driver education and research on how simulators can be used to improve railway technology.
